    摘要: A method and apparatus for scheduling multiuser terminals in a communication system is provided. A receiver receives feedback information from a plurality of user terminals. A user grouping unit selects terminals having a maximum Signal to Interference plus Noise Ratio (SINR) among terminals having the same beam index and beam subset index, from among the plurality of user terminals, and generates terminal groups using the selected terminals, each terminal group including terminals having the same beam subset index. A group scheduling unit calculates a throughput of each of the terminal groups to determine which terminal group has the maximum throughput. A random precoding unit generates random beam vectors corresponding to terminals included in the terminal group determined to have the maximum throughput, and transmits data for user terminals, included in the terminal group determined to have the maximum throughput, over the generated random beam vectors.

    摘要: A method and system for allocating a channel are provided in a communication system including a plurality of Mobile Stations (MSs) and Base Stations (BSs) for providing a communication service to the plurality of MSs. A BS transmits an average Channel Quality Information (CQI) request to MSs. The MSs measure CQI with respect to their channels in response to the request from the BS, compute average CQI from the measured CQI, and transmit the average CQI to the BS. The BS selects a predefined number of MSs according to the average CQI received from the MSs and sets an MS group. The BS transmits a CQI request to the MS group. The MSs of the MS group transmit the CQI to the BS. The BS receives the CQI from the MS group and allocates a channel according to the CQI.

    摘要: An apparatus and method for call setup in a wireless communication system are provided. A first Mobile Station (MS) determines a DownLink (DL) duration, performs synchronization, selects one preamble code among a preamble code set reserved for the call setup of the MS out of the cell area, and transmits the selected preamble code during the determined DL duration. A second MS scans a preamble code during the DL duration, determines if the scanned preamble code is a preamble code for the call setup of the MS out of the cell area, and transmits a response message to the preamble code to the first MS.
